Laptop automatically shut downs after removing the charger. Thought of checking the battery health on HP Support so it showed "Normal"  but still it shuts down and charges to 100% in an instant. 
My device is under warranty ,  so i want to know the solution for this.

You are going to need to make a warranty claim. Can't be done here. It's less than a year since the battery was made but the warranty is one year from purchase of the laptop at retail So I can't say if you are still under warranty. Probably you are. Sounds like the battery needs replacement. It is getting heavy usage but seems to still be a good battery. I can't commit to anything, but it appears HP should replace the battery for you.
